INTRODUCTION
PoweronBoardPowerInvertersaregearedformaintainingtoday'smodernlifewhile
travelinginVans,R Vs,automobiles,trucks,orvehiclethathas12voltbatterypower
supplyandameanstorechargethosebatteries.ThisMaxx1500Inverterissupplied
with:
1.On/Offswitch
2.TripleOutlet
3. DualLEDindicatorsthatindicateoperation(POWER),shutdown(FAULT).
4.Coolingfan
5.A groundingterminalforelectricalsafety.
6.DCcableconnectors
7.Internalprotectivecircuitsthatinclude:
•Automaticoverloadandover-temperatureshutdown(activatedifAC
outputexceedsmaximumpower)
•AutomaticACshort-circuitshutdown.REDFAULT LEDlit.
• Automaticlowvoltageaudiblealarm.
•Automaticlow-voltageshutdown.
•Automatichigh-inputvoltageshutdown.
Maxx1500Series-isastate-of-theart,highlyefficientDCtoACpowerinverterthat
changes12voltsDCfromabatteryto120voltsAC,60Hz.WithproperDCpower,
itcancontinuouslydeliverupto1500wattsAC.
AllPoweronBoardinvertershavetwomethodsofpreventingbatteriesfrombeing
completely discharged. When your batteries begin to dropin voltage,the inverter
will sound an alarm. You can either turn off the inverter or leave it unattended.
Furtherdischargewillautomaticallyturnofftheinverter.Ifyourbatterydoesgoto
complete discharge, it's because some other appliances are drawing power from
thebattery.
This Power Inverter is configured with the latest soft start technology (SST) to
improve inverter operation. Before introduction of soft-start, high startup currents
fromlargeinductive loads couldshutdownthe inverter.Threemajorfeaturesare
incorporatedinSST.First,gradualoutputvoltageramp-upduringinverterstartup.
Thiseliminatesfailedcoldstartsunderload.
Second,outputthatmomentarilydipsinvoltageandquicklyrecovers.Thiseliminates
mostshutdownsfrommomentaryoverloads.
Thispowerinverteralsoincorporatesanewcoolingtechnologythatdirectlybenefits
ourcustomers.Thenew design more efficientlycoolsthepower
transistorsand
combinedwithsoftstartdramaticallyincreasesreliabilityandthelifeoftheproduct.
